Will Bonnie save Damon on ‘The Vampire Diaries’ season finale… or kill him? Find out what the cast is telling us about tomorrow’s episode!

Well, friends, it all comes down to this — Thursday, May 12, marks the season finale of The Vampire Diaries, and it sounds like we’re in for a heart-pounding hour of TV. Will Damon (Ian Somerhalder) really die from the wolf bite? Will Elena (Nina Dobrev) forgive him for everything he’s done? And where the heck did Klaus (Joseph Morgan) go?

HBIC Kat Graham tells HollywoodLife.com we’ll get all the answers we seek, and that we should all “prepare to be gutted.” Oh, and one more thing: We definitely have NOT seen the last of Elijah (Daniel Gillies)!

“You’ll see him in the finale,” Daniel promises, but unfortunately he can’t tell us whether the “bodies” mentioned in last week’s episode have the potential to return as vampires. “That’s a question even Elijah couldn’t answer. “We just don’t know yet.”

Back to Bonnie, the extended preview for the episode shows our favorite teenage witch covered in blood and asking someone for help — and Kat confirms Bonnie is in some serious danger.

“She’s asking for something she can’t do herself,” Kat says of her power-hungry persona. “And if Bonnie can kill Klaus by taking her own life, it must be something pretty big for her to need more help. A lot of what the characters will be going through is: How can we, if at all, save Damon’s life?

That said, werewolf bites have been known send vampires into fits of violent dementia, and Kat tells us: “If he acts out, I don’t think she’s going to hesitate to put him in his place. She’s like me!”

So, wait, does that mean Bonnie will end up having to fight Damon instead of save him? Head to the comments section and start giving me your theories!
